The reconstructed breast has as much trama as the partial mastectomy. I'm 5 months out of surgery and 3 months out of radiation. Still have tenderness, occasional throb and unexpected twinges. Nerves heal and wake up and when they do you know it. Radiation can add to that conditon. I find that if i miss my exercise it can be worse. Scar tightens and muscles get stiff. Be good to yourself and tell your doctor your concerns to ease your mind. I see mine next week and will do the same but I don't know if you ever get accustomed to the new norm.
